This is a nice tract for children. It presents the basics of the gospel in clear, simple terms at a level suitable for younger kids. It's content is comprehensive enough to give a child a sufficient grasp of the gospel message and how to respond to it without further instruction, if need be. However, it is probably best if it is used by a knowledgeable adult to share with a child (and it is written in such a way as to support such interaction) to ensure the child's understanding of the issues involved.

If you are looking for a tract that will assist you in sharing the gospel with a child, I strongly recommend this one for that purpose.
